Download or read book HUMAN PARASITOLOGY written by FATIK BARAN MANDAL and published by PHI Learning Pvt. Ltd.. This book was released on 2015-06-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book, in its Second Edition, has been thoroughly revised considering the feedback received from the readers. The text has been simplified. New information has been added, and at the same time, extra details have been deleted to make the book concise. The new edition introduces a chapter on Medically Important Snails (Chapter 9). We, the human are the host of many parasites, which cause major public health problems, untold suffering and death. Thus, three major groups of parasites—protozoa (flagellates, amoebas, and malarial parasites), helminthes (flukes, tapeworms, and roundworms), and arthropods (insects and arachnids) have been discussed with suitable illustrations. Morphology, lifecycle, mode of transmission, incidence, symptoms, diagnosis, and prevention of medically important parasites have been discussed in light of recent researches. In addition, the chapters, namely, the Evolutionary Aspects of Hosts and Parasites and Present Trends of Parasitic Importance add further value to the book. The book has been written for the undergraduate and postgraduate students of Zoology and other Life Sciences disciplines. In addition, the medical students, public health workers and health professionals also find this text useful. Key Features • Diagrammatical presentation of life cycle of parasites. • Suitably illustrated text. • Discusses the food-borne, water-borne and vector-borne parasitic diseases. • Contains glossary of important terms.
Download or read book Community Organization of Avian Malaria Parasites in Lowland Amazonia written by Linda Marie Elenor Svensson Coelho and published by . This book was released on 2012 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: I characterized a lowland Amazonian assemblage of haemosporidian ("malaria") parasites (Haemoproteus and Plasmodium) of understory birds by analyzing variation in prevalence (proportion of infected host individuals) among years and host species, documenting diversity of haemosporidian evolutionary lineages, and quantifying host specialization. Using standard molecular methods to screen for haemosporidia in 2488 individual birds from 104 species in the Tiputini Biodiversity Station, Ecuador, I found 21.7% to be infected. Prevalence ranged significantly among years and host species. Forty-five putative evolutionary lineages of haemosporidia were identified, by sequencing part of the cytochrome b (cyt b) gene. Based on a comparative analysis, among host species variation in haemosporidian prevalence related positively to level of sexual dimorphism and negatively to foraging height. I assigned 385 parasite individuals to cyt b lineages. These exhibited a wide range of abundance (one to 91 individuals) and host specialization (one to 23 host species). I quantified host specificity by incorporating both phylogenetic relationships (based on genetic data) and frequency distribution among hosts. Based on null model comparisons, six haemosporidian lineages were more specialized than expected by chance. The hosts of these six haemosporidian lineages were on average more abundant than hosts of generalist lineages, but average body size and survival rate did not differ between hosts of specialists and hosts of generalists. Host specificity was also phylogenetically conserved among haemosporidia. Consequently, I performed a comparative regression analysis, controlling for the effect of parasite phylogeny, and found no relationships between host specificity and host abundance, body size, or survival rate. Finally, I applied network analysis in combination with null models to test whether the level of reciprocal specialization (where one parasite lineage associates with only one bird species, which harbors no other parasite lineages) is greater in this tropical assemblage than it is in an equivalent temperate assemblage. Assuming coevolution proceeds towards reciprocal specialization, it should be greater in the tropics, where coevolution has historically been hypothesized to be more important in species diversification. I found no evidence for this hypothesis; instead, reciprocal specialization was greater in the temperate site.
Download or read book Avian Malaria and Related Parasites in the Tropics written by Diego Santiago-Alarcon and published by Springer Nature. This book was released on 2020-10-19 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.
Download or read book Avian Malaria in the Asian Tropical Subregion written by Marshall Laird and published by . This book was released on 1998 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marshall Lairds Avian Malaria In The Asian Tropical Subregion will be only the second book to be devoted solely to the species of Plasmodium parasitising birds. The first, Redginal Hewitts Bird Malaria, Baltimore, The Johns Hopkins Press, appeared in 1940, and was largely devoted to relevant laboratory investigations. A number of additional species of these parasites had been described by 1966, when the late Professor Cyril Garnhams classic Malaria Parasites And Other Haemosporidia was published (Blackwell, Oxford), eight of the fifty chapters of which concerned the true avian malaria parasites and have since remained the standard reference. The present book is particularly timely in bringing the whole subject up to date for a huge tropical part of the globe, which is at the same time at the heart of a widespread network of migratory bird species; many of which it demonstrates to carry important species of plasmodia in their blood. The authors findings, which demonstrate the presence of most of the valid species of bird malaria parasites and a single highly distinct new one in the Asian Tropical Subregion and its eastern and western borders, will serve as a source for the sure identification of these; illustrated as it is by high quality photomicrographs from many of the 536 individual birds of 180 species found Pl - +ve, thanks to MAPS.

Available in PDF, EPUB and Kindle. Book excerpt: Every researcher or diagnostician working with reptiles has faced the challenge of identifying reptile hemoparasites and then determining whether they are of importance or merely incidental. Another challenge is how to easily find the information required to make the proper identification. A distillation of knowledge from world-renowned expert Sam R. Telford, Jr, Hemoparasites of the Reptilia: Color Atlas and Text provides a comprehensive compilation of information on how to differentiate between the myriad species of reptile hemoparasites. The atlas provides diagnoses for 262 species of plasmodiids, hemogregarines, hemococcidians, trypansosomes, and leishmanias, including descriptions of eight new species or new taxonomic designations. It also discusses lesser known groups, such as piroplasms, rickettsiae, chlamydia, and erythrocytic viruses. Each genus and many species are represented among the 166 taxa illustrated in color. The species accounts contain host and geographic distribution, with precise localities when possible, prevalence, life cycles and vectors when known, effects upon the host, and ecology of the host-parasite relationship, morphological variation, and an exhaustive bibliography. The book also includes an illustrated key showing diagnostic characters. Telford draws on his 45 years of experience and his personal collection, considered the world’s most complete, to provide information on the morphology of the unicellular parasites of reptilian blood. He includes information from hard-to-find original papers and articles from sources throughout the world. The illustrated key and photomicrographs from Telford’s collection make identifying species quicker and easier.

Download or read book Parasite Infections From Experimental Models to Natural Systems written by Toni Aebischer and published by Frontiers Media SA. This book was released on 2018-07-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eukaryotic parasites (including parasitic protozoans, worms and arthropods) are more complex and heterogeneous organisms than pathogenic bacteria and viruses. This notion implies different evolutionary strategies of host exploitation. Typically, parasites establish long-term infections and induce relatively little mortality, as they often limit pathological changes by modulating host cells and downregulating adverse immune responses. Their pattern of distribution tends to be endemic rather than epidemic. Despite these seemingly benign traits, parasites usually cause substantial chronic morbidity, thus constituting an enormous socioeconomic burden in humans, particularly in resource poor countries, and in livestock worldwide. Parasite-induced fitness costs are an evolutionary force that can shape populations and contribute to species diversity. Therefore, a thorough understanding of parasites and parasitic diseases requires detailed knowledge of the respective biochemical, molecular and immunological aspects as well as of population genetics, epidemiology and ecology. This Research Topic (RT) bridges disciplines to connect molecular, immunological and wildlife aspects of parasitic infections. The RT puts emphases on four groups of parasites: Plasmodium, Toxoplasma, Giardia and intestinal helminths. Co-infections are also covered by the RT as they represent the most common form of parasite infections in wildlife and domestic animal populations. Within the four types of parasites the following topics are addressed: (1) Experimental models: hypothesis testing, translation and limits. (2) Critical appraisal of experimental models. (3) Natural systems: Technological advances for investigations in natural parasite-host systems and studies in natural systems. (4) The urgent need for better models and methods in natural parasite systems. Hence, the RT covers and illustrate by the means of four main parasitic infections the parasite-host system at the molecular, cellular and organismic level.

Download or read book Saving Lives Buying Time written by Institute of Medicine and published by National Academies Press. This book was released on 2004-09-09 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 50 years, low-cost antimalarial drugs silently saved millions of lives and cured billions of debilitating infections. Today, however, these drugs no longer work against the deadliest form of malaria that exists throughout the world. Malaria deaths in sub-Saharan Africaâ€"currently just over one million per yearâ€"are rising because of increased resistance to the old, inexpensive drugs. Although effective new drugs called "artemisinins" are available, they are unaffordable for the majority of the affected population, even at a cost of one dollar per course. Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance examines the history of malaria treatments, provides an overview of the current drug crisis, and offers recommendations on maximizing access to and effectiveness of antimalarial drugs. The book finds that most people in endemic countries will not have access to currently effective combination treatments, which should include an artemisinin, without financing from the global community. Without funding for effective treatment, malaria mortality could double over the next 10 to 20 years and transmission will intensify.
